This Demonstration synthesizes both single tones (upper channel) and melodies (lower channel). It can produce different waveforms and harmonics. The duration (in seconds) and the fundamental note, on an equal-tempered scale, can also be changed.

The sliders following the fundamental control the number and intensity of the harmonics, which are integer multiples of the fundamental frequency. Songs are listed in alphabetical order. Songs are not affected by the fundamental and duration controls.
